BIOGRAPHY
He Jiashu plays the younger version of Cheng Yichen in Double Helix (2026), a Mandarin-language boys’ love (BL) drama adapted from Lan Lin’s danmei novel A Round Trip to Love, opposite Fa Xuange’s Qin Lang in the series’ parallel second-couple storyline.
Public biographical information about this performer, including birth date, age, hometown, education, and talent agency, could not be confirmed through any official or independently verifiable source. The character billing as “Young Cheng Yichen” and the absence of any prior screen credit suggest this may be an early or debut professional role, and the performer’s age cannot be confirmed to be 18 or older. In line with site policy, no age-sensitive personal details are published on this profile until independently verified.
BLGLFlix editorial view
The billing is Young Cheng Yichen. There is an entire category of performer who exists only in other people’s flashbacks, and almost none of them are documented anywhere.
He Jiashu plays the younger version of Cheng Yichen in Double Helix, which takes its story from A Round Trip to Love, the danmei novel by Lan Lin, opposite Fa Xuange in the second-couple thread. That is the only credit, and the character exists to make an adult’s history legible.
Nothing about the performer could be confirmed. No birth date, no hometown, no agency, no earlier work. Because the role is a younger self and there is no prior credit, this may well be a first job, and there is no way to establish that the person is eighteen.
So this page publishes nothing age-sensitive at all. Not the fields we would withhold for a known minor, and not the fields we would fill for a known adult. When age cannot be established, the safer assumption is applied, and it is applied here without waiting for anyone to confirm it.
